Thank you for your question. Unfortunately, the available resources from Milwaukee don't indicate this 42-68-0800 side handle clamp's inside diameter. But if this may be of help, this clamp is used for the following Milwaukee drills: 0100-20, 0200-20, 0201-20, 0202-20, 0202-50, 0299-20, 0300-20, 0300-50, 0301-20, 0302-20, 0302-50, and 0302-55. If your drill is one of those mentioned above, then, this is the side handle clamp that you need. If not, please give us the make and the model number of your drill so we can help you look for the side handle clamp that works for it. Thanks for seeking answers from PlumbersStock.com!
